  • Patent number: 11767893
    Abstract: Methods and systems are provided for sensing a clutch position. In one example, a method may include generating a single output signal by combining at least an output of a first sensor and an output of a second sensor output, the first sensor and second sensor connected in parallel, and the first sensor and the second sensor sensing a common moving element of a clutch. In one example, the method may further include a first sensor output and a second sensor output provided on a common sensor bus. As another example, the first sensor output may be a master pulse width modulation output, and the second sensor output follows a modulation frequency of the first sensor output.
